# action of a torus on a projective space

How can a torus $T^n$ acts on the projective space $\mathbb{P}^n=\mathbb{P}(\mathbb{C}^{n+1})$?

Is it possible or I'm doing a mistake because I need to consider $\mathbb{P}^{n-1}$ ?

Thanks

It can act trivially, for example... You probably have in mind something more specific that just any action. –  Mariano Suárez-Alvarez Feb 29 '12 at 18:24
